Background:

MG-277, a molecular glue degrader, effectively induces degradation of a translation termination factor, GSPT1, with a DC50 of 1.3 nM. MG-277 potently inhibits tumor cell growth in a p53-independent manner, with IC50s of 3.5 nM for RS4;11 cells and 3.4 nM for p53 mutant RS4;11/IRMI-2 cells, respectively. Anticancer activity[1].

MG-277 (0.03-10 nM; 24 hours; RS4;11 cells) treatment inhibits cell growth and degrades GSPT1[1].MG277 has a significantly decreased potency in reducing the level of MDM2 protein in cells and fails to activate wild-type p53. MG-277 is highly potent and effective in inhibition of cell growth in cancer cell lines with wild-type p53, mutated p53, or deleted p53, indicating a p53-independent mechanism. MG-277 induces rapid GSPT1 degradation in cancer cells in a p53- and MDM2-independent manner but in a manner dependent upon cereblon, CUL4 E3 ubiquitin ligase, and proteasomes[1].
